Backbone Double is the stairway Backbone system with double backbone that allows to create linear stairways, with or without landings, with railings both in stainless steel and glass. The benefits to have two or more “backbones” joined each other by horizontal elements are numerous:
• possibility of reaching larger widths
• to have structures with higher resistance
• to avoid (in some cases) supporting elements (floor or wall accessories)
• to increase the support points of the glass tread reducing its dimensions.
